the three forms of heat transfer are convection, conduction and radiation. heat can be transferred through
, fluid currents, and electromagnetic waves. heat energy always flows from
to cold, and will continue to flow until both materials reach
temperature.

the same

Explanation:

To solve this fill - in - the - blank problem about heat transfer, we analyze each blank:

First Blank

We know that the three forms of heat transfer are convection, conduction, and radiation. Conduction is the transfer of heat through direct contact between materials. Convection is through fluid currents, and radiation is through electromagnetic waves. So the first blank should be filled with "direct contact".

Second Blank

According to the principle of heat transfer, heat energy always flows from a region of higher temperature (hot) to a region of lower temperature (cold). So the second blank is "hot".

Third Blank

Heat transfer continues until the two materials reach thermal equilibrium, which means they have the same temperature. So the third blank is "the same".

Answer:

First blank: direct contact
Second blank: hot
Third blank: the same
